From Fermilab Today: First cavity in Cryomodule 2 achieves goal gradient

9 January 2014 On 20 December, members of the Accelerator Division SRF Electron Linac Department and the Technical Division SRF Development Department successfully brought the first accelerating cavity in Cryomodule 2 to a gradient of 31.5 megavolts per meter, the gradient required for the proposed International Linear Collider. The achievement demonstrates the cavity's successful integration into the cryomodule. Category: Feature | Tagged: , , ,

Asian collaboration on ILC superconducting radiofrequency technologies

| 24 January 2013 When the New Year’s bell was still echoing in the air, physicists from China and Japan gathered in Beijing to attend the fifth IHEP-KEK collaboration meeting on 1.3-GHz superconducting radiofrequency (SRF) technology which was held at the Institute of High Energy Physics (IHEP), Chinese Academy of Sciences from 7 to 8 January 2013. Six high-energy accelerator experts from KEK and Kyoto University and nearly twenty physicists from IHEP participated. Category: Around the World | Tagged: ,

Quench

| 4 October 2012 What is a quench? Everything has a limit—superconducting cavities are no exception. Physicists put voltage in their superconducting cavities to boost the energy of particles. But it’s possible to ask for too much from a cavity. When this happens, the cavity fails: the superconducting material becomes normal-conducting, the voltage collapses and the energy escapes. This is called a quench. Category: LCpedia | Tagged: , ,

Baseline Technical Review for ILC superconducting RF systems

| 9 February 2012 On 19 and 20 January 2012, the third Baseline Technical Review to finalise the Technical Design Report baseline was held at KEK laboratory in Japan. The meeting reviewed the proposed cavity gradient performance, cavity integration, and the main linac integration and interfaces to the ILC conventional facilities, including radiofrequency power, control and interfaces to conventional facilities. A special meeting on superconducting radiofrequency costs followed this meeting on 21 January. Category: Director's Corner | Tagged: , , , , , ,

Thoughts from Granada – a view from the back of the room

| 27 October 2011 Superconducting radiofrequency technology is advancing, the ILC design is coming together, and the LHC programme is running exceptionally well, although the evidence for new physics remains tantalizing. The linear collider community is well on its way to bringing the next big particle collider to the world's stage. Category: Director's Corner | Tagged: , ,

Superconducting RF cavity industrialisation

| 17 June 2010 Producing high gradient superconducting radiofrequency (SCRF) cavities that meet our demanding performance goals, are affordable and can be produced by industry represents one of the largest challenges on the way to making a solid project proposal for the ILC. [...] Developing a worldwide capability to produce our cavities in industry represents an enormous challenge - one we need to address now. Category: Director's Corner | Tagged: , , , ,

Global effort for high-gradient ILC SCRF cavities

| 30 July 2009 I would like to thank Barry Barish (...) for the opportunity to write his column and expand on the efforts for an area of the Main Linac and Superconducting Radiofrequency (ML-SCRF) technology and the tasks ahead of us. Category: Director's Corner | Tagged: , , , ,

Past successes in superconducting RF are a good omen for the ILC

26 February 2009 One of the high-value R&D programmes for the ILC is to reliably reach gradients of 35 Megavolts per metre (MV/m) in one-metre long (9-cell, 1.3-Gigahertz) niobium cavities, the heart of the main linac. More than a dozen such cavities have demonstrated gradients between 35 and 40 MV/m at DESY, and more recently at Jlab. The challenge is to hit such performance levels nearly every time, and with nearly every cavity! This means that we need to conduct some good science to understand the basic nature of the gradient limits, and clever engineering to invent methods to overcome these. Category: Feature | Tagged: ,

Plug compatibility: rationale and technical aspects addressed

| 15 January 2009 An interesting and challenging concept that has emerged in developing the ILC's technical design is that of plug compatibility for the superconducting radio frequency accelerating systems. Category: Director's Corner | Tagged: ,

Progress in the SCRF technical area

| 30 October 2008 As one of Project Managers for the ILC I was been given the current task of overseeing superconducting radiofrequency technology (SCRF) in August 2007, and it may be a good time to see how our SCRF technical area could make some progress with global cooperation.
